IMPROVEMENT lN SHUTTLES FOR NARROW-WARE LOOMS.

Specification forming part of Letters Patent No. 187,369, dated February13, 1877; application filed January 11, 1877.

To all whom it may concern:

Be it known that we, GEORGE FISCHER, GEORGE F. KEK, and JAMES B. SHARP,of the city, county, and State of New York, have invented a new anduseful Improvement in Shuttles for Looms, which improvement is fully setforth in the following Specification, reference being had to theaccompanying drawing, in Which Figure 1 represents a plan or top view ofa shuttle containing our improvement. Fig. 2

- is a longitudinal section thereof in the plane a; :17, Fig. 1.

Similar letters indicate corresponding parts.

This invention relates to certain improvements in tension devices forshuttles used in narrow-ware looms; and consists in combin ing with thebody of a shuttle having an eye and a recess, a fixed cross-bar and alongitudinal pressure-slide, both arranged in said recess as hereinafterdescribed, the said pressure-slide having a book, which partly embracesand bears against the fixed cross-bar, so that the filling-thread can bebrought with in said hook, between the same and the fixed bar, and thusform a tension device for the thread.

In the drawing, the letter A designates a shuttle of the kind commonlyused in looms for weaving narrow fabrics. B is the pressure-slide, and Ois'a stationary bar, which parts are arranged in a recess, D, formed onthe front part of the shuttle A at the point where the eye a is formed,the recess being made to intersect the eye. The stationary bar 0 extendsacross the recess D, and is situated adjacent to the eye a.

The pressure-slide B consists of a piece of wire bent at one end to forma hook, I), and

which is subjected to the action of aspring, E, .having a tendency toforce said slide toward the bar.

When the filling-thread is run from the spool through the eye a, thepressure-slide B is pushed or forced back by hand so that the thread iscaught in the hook b, and hence when the pressure slide B is releasedthe thread is forced up against the stationary bar 0 and is held with auniform tension.

The pressure-slide B is so arranged that it can be removed if desirable;and, moreover, if preferred, it can be made of a solid piece of metal orother material of the general shape shown, instead of wire.

It will be seen that the filling-thread can be brought Within the hookI) of the pressure-slide with great facility, and hence a very importantadvantage is obtained by our invention over the old class of tensiondevices.

It mu t be remarked that our tension device admits of variousmodificationsfor instance, the spring itself might be made to act as thepressure-slide, the thread being passed through between the end of thespring and the stationary bar; but in this case the stationary bar mustbe of a fork so as to support the filling-thread, whereas in the exampleshown in the drawing the pressure-slide itself forms a support for saidthread, as previously stated.

What we claim as new, and desire to secure by Letters Patent, is

1. The shuttle A, constructed with the eye a, and recess D, intersectingsaid eye with a fixed bar, 0, secured transversely in said recess, andwith a longitudinal horizontallymoving pressure-slide bearing againstsaid cross-bar, substantially as described.

2. The combination, with a loom-shuttle body, constructed with an eye,a, and a recess, D, of the fixed bar 0, arranged transversely across theopening D, and adjacent to the eye a, the pressure-slide B, arrangedlongitudinally in said recess, and having a hook, b, bearing against thecross-bar 0, substantially as described.

In testimony that we claim the foregoing we have hereunto set our handsand seals this 9th day of January, 1877.
